Grooveshark, the online music service that let’s you type in a song, artist or album and instantly hear the music is going mobile. If you have a Palmpre or Blackberry (sorry Storm owners, won’t work here) you can get Grooveshark Mobile music service for just $3 a month. For those of you moaning that it’s not free it is still $10 cheaper than satellite. Compared to Pandora and Slacker which give you pre-programed streaming music and also have mobile versions, the big difference is that Grooveshark let’s you choose the songs directly.
